Secondary Hyperparathyroidism Anatomy
To better understand secondary hyperparathyroidism, it helps to understand the anatomy of the parathyroid glands.
The four parathyroid glands are located in the neck, embedded inside of the thyroid gland.
The parathyroid glands produce parathyroid hormone, which regulates the level of calcium in the bloodstream.
